Finding the right sports bra for running is tough.

Over the past month, Ive put this bra through 56 kilometers of running and a few strength workouts.

First impressions

When I first put the Performance Flex Bra on, I had mixed feelings.

The straps looked notably thick, and I worried they might dig into my shoulders.

But they turned out to be surprisingly light and comfortable.

Theres nothing more annoying than struggling to wrestle off a wet sports bra after a sweaty session.

One of the biggest perks I found while testing this sports bra is its sweat-wicking abilities.

Thats impressive, considering how much heat and sweat can build up and cause irritation during long-distance training.

This sports bra is a medium support bra, and I’d say it lived up to this.

It didn’t feel overly compressive, but I felt adequately supported as I ran.

I also noted the level of breathability the bra had to offer.
